On Tuesday, you can vote by tweet and Facebook for your favorite Central New York charity. The nonprofit with the most hashtag tweets and Facebook posts by the end of the day - called Giving Tuesday -- will get $5,000 from the Central New York Community Foundation.

The hashtag is #GivingTuesdayCNY. You can also vote on the Community Foundation's Facebook page.

This is the second year for the national campaign and the first year that the Community Foundation is participating, said Crystal Smith, a spokeswoman for the event.

Organizations are already lobbying for Central New Yorkers' two votes. (You can vote once on Facebook and once on Twitter). Syracuse Opera has already sent out a "Save the Date" reminder explaining the rules and reminding people to vote.

Only the tweets and Facebook posts logged on Dec. 3 will count toward the each organization's tally.
